[win/asan] Improve SharedReAlloc with HEAP_REALLOC_IN_PLACE_ONLY. (#132558)

Currently with HEAP_REALLOC_IN_PLACE_ONLY a new allocation
gets returned with the content copied from the original pointer,
which gets freed.

But applications may rely on HEAP_REALLOC_IN_PLACE_ONLY returning
the same pointer as they give as input to e.g. RtlReAllocateHeap.
If e.g. growing is not possible it fails without
modifying the input pointer.

Downside of this patch is, it won't detect accesses to the area
getting "free" by a shrinking reallocation.

The LLVM Compiler Infrastructure

OpenSSF Scorecard OpenSSF Best Practices libc++

Welcome to the LLVM project!

This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.

The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.

C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.

Other components include: the libc++ C++ standard library, the LLD linker, and more.

Getting the Source Code and Building LLVM

Consult the Getting Started with LLVM page for information on building and running LLVM.

For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.

Getting in touch

Join the LLVM Discourse forums, Discord chat, LLVM Office Hours or Regular sync-ups.

The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
